Abstract (en)
[origin: US2020200143A1] A vertical axis wind energy power turbine having a hollow shaft on which are attached, rotating and fixed components with outer-surface shapes, fixed vanes, and integral heating to concentrate without confining airflow, an overspin-limiting power-enhancing self-engaging flywheel, and, conversion systems for both, pumped air that may be transferred through hollow mountings to do other work, and, for electricity generation.
